Well, If you are remastering a cd it would not matter because the cd is less than 2 gig. But I like using a dvd. Same size disk much more room. The problem I have run into remastering the dvd is determining what files have to remain in the KNOPPIX file and what can be moved into the KNOPPIX2 file. I have asked here a couple of times but never got an answer. Then once you figure out how to divide up the /usr directory how do you go about creating a cloop file with part of a directory? At any rate I do not think that the limit is with the iso 9660. Is there another format that will produce a bootable disk? I think that it must be with cloop. I am looking at this live dvd distro with a single 3.88 gig file and an isolinux (boot) directory. If I could use squash fs and remaster Knoppix the same way, there would be no need to split directories and files in directories to keep the file size under 2 gig.
